refactor: Mods view (#134)

* feat: add UI skeleton for new mods interface

* fix: only apply app menu style to app menu items

* feat: add menu skeleton

* feat: add thunderstore mods view into mods view

* refactor: remove thunderstore mods view from router + menu bar

* refactor: move search input into mods view

* fix: adjust ts mods container padding

* refactor: center pagination components

* refactor: rework media queries to adapt cards container width

* fix: set mods view navigation min-width

* refactor: compute mods container width with CSS variables

* refactor: remove horizontal padding around ts mods container

This will allow them to take much screen space.

* feat: Thunderstore mods container is larger

* feat: add layouts for 5 to 8 Thunderstore mod columns

* feat: add some space to separate navigation menu subparts

* fix: move search pagination reset in ThunderstoreModsView component

* feat: retrieve Thunderstore mod categories when fetching mods

* feat: add mod categories selector component

* feat: mod categories selector now filters Thunderstore mods

* fix: reset pagination index if needed when selecting mod categories

* fix: first mod does not appear anymore while selecting any mod category

First mod's categories array was used as an accumulator (in a reduce call)
to regroup all mod categories; we now use an empty array as initial value
for the accumulator.

* feat: add a selector component to sort mods

* feat: set sort selector default value on view mount

* fix: set default sorting select value as selected in dropdown list

* feat: add date_updated field to ThunderstoreMod type

* feat: pass sorting value to ThunderstoreModsView as a prop

* feat: mods can be sorted by name and release date

* feat: mods can be sorted by most downloaded and top rated

* fix: don't display sorting select on local mods view

* refactor: remove local mods title

* refactor: export local mods view code in dedicated component

* refactor: export search value in a search-dedicated store

* fix: display "no matching mods" message when no mods match

This message was previously displayed only if no mods matched AND search
input was not empty; now that we have categories selector, we can have no
matching mods with an empty input.

* refactor: remove unused input prop

* fix: mods can be sorted by rating

* refactor: remove unused searchValue computed property

* style: adjust SortOptions import

* refactor: move selected mod categories into search store module

* refactor: move mod sorting into search store module

* refactor: export mods menu component to dedicated file

* fix: remove compare method initialization

* feat: local mods can be filtered with search input

* build: add ES2018 lib to typescript compiler options

* refactor: remove unused variable

* fix: retrieve SortOptions values from string input

* refactor: move Thunderstore mods view into dedicated folder

* style: add missing trailing newline to SortOptions.d.ts
